For me, the award for Best Tone goes to Mike Inez. That Warwick/Fishman bass redefined "angry piano".
The bass was very well represented in the live stream throughout, apart from Pantera, oddly, which was a real shame as Rex is one of my favourite bassists. As it turned out Pantera were probably my biggest disappointment of the day though overall. What the hell was Zakk Wylde doing?!
